Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed November 10, 1906. Serial No. 342,832.

To all whom it may concern:

Be it known that I, STEPHEN H. CooMBs, a resident of Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Beaters, of which the following is a full, clear, and exact description.

The present invention relates to devices for beating or whipping cake-batter, cream, eggs, etc.

The invention designs to provide a device for the purposes stated which is simple in construction, and efiicient in operation. It is well known in the art that the most effective and quickest method of beating batter etc., to make it light, is by using two ladles or paddles one in each hand, and beating the material by continuous circular motion of each ladle in paths intersecting each other, and the invention also designs to provide an improved device in which the beating operation is substantially the same as the familiar paddles to affect the material in the same manner as when it is done by hand but with greater speed.

In the operation of the beaters embodying the inventions set forth in Letters Patent of the United States No. 573,208 and No. 673,198, granted to me, in which the beaters are respectively connected to cranks revolving in opposite directions, the beater-blades are moved laterally in the same direction and vertically in opposite directions, it being impossible when oppositely rotating cranks, which are directly connected to the beater-levers are employed to attain both vertical and lateral movement of the beater-blades in opposite directions.

The present invention also designs to provide an improved construction in which a simple operating mechanism can be used and a plurality of beaters may be driven by cranks oppositely disposed and rotating in the same direction to cause the blades to move laterally and vertically in opposite directions relatively.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claim at the conclusion hereof.

In the drawings: Figure 1 is a view in side elevation of a device embodying the invention, the batter-pan being shown in section. Fig. 1 is a detail view of the supporting-frame. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is a section on line 33 of Fig. 1. Fig. 4 is a section on line 44 of Fig. 1. Fig. 5 is an end elevation of the device, the batter-pan being shown in section. Fig. 6 is a horizontal section taken on line 66 of Fig. 5. Fig. 7 is a side-elevation of a device embodying a modified form of the invention. Fig. 8 is a vertical section thereof, and Fig. 9 is a plan of the adjustable pan-support.

In the form of the invention illustrated in Figs. 1 to 6, the device is adapted to rest on the top of a batterpan 12, of usual form, and' to be held in operative position thereon by the operator, this form being one more generally used for the smaller sizes of beaters and in households. A supporting-frame adapted to rest on the pan and in which the operating parts of the device are mounted, comprises a pair of arched bars 13 having legs and feet 14 adapted to fit around the upper edge of the batter-pan to centralize and position the device with respect to the pan or bowl. These arched bars are preferably formed of a strip of metal bent to form the legs and feet. A pair of frame-bars are riveted to the arch-bars as at 16 and are extended inwardly therefrom to form uprights 17 which are secured together and between these uprights the bearings and guides for the operating parts are mounted. The bars from which the frame-members 17 are formed are also extended upwardly from the points at which they are secured to the arch-bars to form braces 18 extending upward diagonally and secured to the uprights as at 19 to render the supporting-frame laterally rigid. This construction and arrangement of the supporting-frame provides a simple way of forming a rigid frame from the bars or strips of metal which can be readily formed by dies. To the upper ends of the uprights of the supporting-frame is secured a handle 20 whereby the device and frame can be held downwardly upon the .batterpan and to hold the device in operative relation with respect thereto.

A bushing or journal sleeve 21 is secured between outwardly bent portions 17 of uprights 17 to provide a journal for a main drive-shaft 22. At one side of the frame the drive-shaft has secured thereto a gear 23 and to its other end a crank or handle 24 whereby the operator can impart movement to the drive-shaft. Below the drive-shaft a bushing or bearing-sleeve 25 is secured between outwardly bent portions of the uprights in which a crank-shaft 26 is journaled. A pinion 27 secured to shaft 26 meshes with and is driven by, gear-wheel 23. To the opposite ends of shaft 26 are respectively secured oppositely disposed cranks 28 and 29 whereby the beater-levers are respectively operated each crank being provided with a wrist-pin 351 Beater-blades 30 each comprise a pair of inwardly eX- tending arms 31 and a connection-portion arranged at the outer side. Each beater-blade is secured to a beater-lever 15 or support preferably (but not essentially) formed of a rod or strip which is bent to form a pair of upright members 32 which extend upwardly from the beater and are bent towards each other as at 33 and between said bent portions is secured a cross head or block 34 to which an eccentric-pin 35 is connected. A rivet 37 extending through block 34 and the uprights, rigidly secures the block to the uprights. The members of the beater-levers are also spread as at 38 to clear the main drive-shaft and operating-handle during the operation of the device. A stud or tube 39 is secured between the uprights oi the supporting-frame and the upper portions of the members of the beaterlevers are bent to form ways for stud 39 and by which the upper ends of the levers are slidably connected to the frame so they can move vertically. By providing guides at one end, for one end of each lever, and eccentric connections between tho guides and the blades there is less angular movement of the levers which renders them easy to operate.

In operation, movement, manually imparted to the operating-crank or handle 24 will drive gear 23 which in turn will rapidly rotate pinion 27 to impart continuous rotation in one direction to the cranks 28 and 29 and wrist-pins 35. The oppositely disposed eccentric connections between the beater-levers and the operating-means rotating in the same direction will operate the levers and beaters to travel in opposite directions both laterally and vertically and continuously stir the batter, e., the batter will be beaten to move in a substantially elliptical path the same as is done when using two paddles to stir the batter. This has been found in practice to be a most efficient movement and to result in making the batter light.

In Figs. 7 to 9, there is shown a modified form of the invention which is designed more particularly for the larger sizes of heaters and in which a different supporting-frame is provided. In this form of the invention the frame comprises an arch 40 and a standard 41 secured thereto at its upper end and also by a curved strip 42. The main operating-shaft 43 is journaled in uprights 41 and a standard 41 secured at its upper end to arch-bar 40 and at its lower end to a cross-bar 41 One end of drive-shaft 43 has secured thereto a gear-wheel 44 arranged to engage a pinion 45 which is connected to drive a fly-wheel 46. In this construction the eccentric-shaft 26 and guides 39 are mounted in standard 41. The operating-mechanism for the heaters is the same as that hereinbefore described. An adjustable pan-support comprises two members which are formed of a bar bent as at 48 to fit around the pan and secured together by blocks 49. The ends of the pan-supporting bars extendoutwardly alongside of the bars 40 to guide the support vertically. To adjustably sustain the pansupport at the desired elevation, the bars 40 have formed therein notches or teeth 50 which are adapted to be engaged by and hold dogs 51 which are pivotally sustained in the pan-support as at 52. The dogs are provided with extensions 53 which may serve as weights to hold them in operative position. When the dogs are released, the pan-support is free to be lowered. Stops 54 may be provided for the pan-support. @The invention provides a simple construction for a device of the character described which has been found to be most efiicient in practice. It possesses several important advantages. It provides an advantageous movement for the heaters. By providing guides at the upper ends of the levers less power is required to operate the levers and beaters than heretofore. The supporting-frame, being made by dies, can be produced at a low cost.

The invention is not to be understood as restricted to the details set forth and described but may be modified by the skilled mechanic without departing from the spirit and scope of the invention.
